Predicted to enable several functions, including ATP binding activity; activin binding activity; and activin receptor activity, type I. Predicted to contribute to activin-activated receptor activity and growth factor binding activity. Involved in central nervous system development; development of primary female sexual characteristics; and positive regulation of nitrogen compound metabolic process. Predicted to be located in cell surface and cytosol. Predicted to be integral component of plasma membrane. Predicted to be part of activin receptor complex. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human ACVR1B (activin A receptor type 1B).
